GEORGE W. GOMBER, OF CONYNGHAM, PENNSYLVANIA, ASSIGNOR TO A. W. DRAKE MANUFACTURING ('10., 0F HAZLE'ION, PENNSYLVANIA, A CORPORATION OF PENN- SYLVAN IA.

Application filed June 8, 1920. Serial No. 387,380;

This invention relates to cork extractors.

The object of the invention is to provide a combination cork screw and cork pulling device whereby corks projecting a sufficient distance without the bottle can be readily pulled without using the cork screw, while corks leaving but little -or no hold may be pulled in the usual way with the cocrk screw.

A further object of the invention is to provide a novel form of cork screw which will notbreak up the cork as does the ordinary form of'coil cork screw and which will secure a stronger pulling hold on the cork and will enter the cork more easily.

The device of the present invention will H be found to be very efficient in pulling'corks which can not be removed in the usual way by prying or, without breaking into small pieces.

of cork The invention will"be' best understood from a consideration of the following detailed description taken in connection with theaccompanying drawing forming part of this specification, with the understanding, however, that the inventlon is not confined to any strict conformity with the showing in the drawing, but may be changed andmodified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a perspective view of the preferred embodiment of the invention.

Fig. 2 is a detail partly in cross-section of one of the jaws illustrating the manner of attaching the cork screw to said'jaw.

Fig. 3 is a cross-section illustrating the manner in which the rolled section for holding the cork screw on the jaw is formed.

Fig. 4 is a longitudinal cross section of that portion of the cork screw projecting beyond the aw.

The device of the invention comprises substantially a pair of pivoted levers each havin a jaw to one of which a novel form screw is secured. The handles or levers are designated by the numeral 5 and Specif cation of Letters Patent.

the aws by the numerals 6 and 7. One of the aws 7 1s bent to provide a concave gripping face 8 having serrations or teeth runnmg transversely thereof. The other aw 6 has a gripping face 9 which is 'substan,'

so that when 'they'are closed their outerv edges meet. The aw 6, which'has the plane gripping 'face 9, is provided with a roll. 10.

This roll receives the end ofa cork screw '12 ofpeculiar form. The cork screw l2may be held within the roll by an ordinary screw head and by its threads 14, or it may be soldered therein, In the illustrated embodiment of the'invention, the cork screw 12 is held within the roll by providing a depression or groove 13 in the shank'the'reof and by pressing down the roll, as'at 11, to fit into the groove 13 whereby longitudinal movement in either direction of the screw with respect to the roll is prevented. The roll 10 terminates with the outer edge or end of the gripping sur'face'9, while the threaded portion of the screw projects outwardly from the jaw 6 so as to form a substantial continuation thereof.

The cork screw 12 is formed something like a wood screw but is more tapering, is of greater pitch, and is more deeply milled than the ordinary wood screw. The screw might bev described as comprising'a solid shank oftaperlng diameter havlng a thread of a depth which progressivelyincreases as the shank tapers. This statement will be best understood from an inspection of Fig. 4 of the drawing. In other words, the threads are deepest where the shank tapers the most.

Tests have shown that deeply milled screws of the form shown in the drawings will secure a stronger pulling hold on the cork than a coil screw, will start to enter the cork more easily, can be kept in the center of the cork, and that with them the corks can be pulled with very little breaking up as compared with the ordinary coil screw.

In case the cork projects a suflicient distance beyond the bottle to allow a good hold to be obtained, the gripping faces 8 and 9 of the jaws may be closed about the cork, whereupon the same may be readily pulled without any possibility of mutilation of the cork.

, wardly, whereupon themost obstinate cork will giveway. Fromwhat has been said,it should be clear that the levers have an in- I timate cooperation with the screw, and the screw with the levers in effecting the single result of extracting corks. The screw can-' not be used independently of the handles,

nor the levers independently of the screw, without sacrificing most of the advantages lmien the screw portion of the extractor is used, the handles or leverswhen sepa rated render the turning of the screw into even a tight cork a very easy operation.

After the screw has become embedded its full length in the cork, the free jaw 7 may be closed, whereupon if the cork is well into the bottle the jaw will lie over the top of the bottle and provide a convenient fulcrum for starting the cork. The roll 10 and jaw 9 serve as a head for the screw, preventing entrance of the lever into the hole in the cork cut bycthe screw. i When the'pivoted handles are used, they a give sufiicient, leverage for gripping and holding new and tight corks. If desired,

after the cork is gripped between the jaws,

, the two handleson one side and the 'screw on the other side may be grasped by the fingers and the entire implement pulled upof a my invention.

a In some forms of the invention it may be A advisable to employ the ordinary coil screw,

and in, certain of the claims I have provided for this. i i j What is claimed is: a 1. A cork extractor comprising a pair of pivoted levers having jaws, and a screw mounted on one of the jaws and extending outwardly and longitudinally therefrom.

2. A cork extractor comprising a pair of pivoted levers having jaws, and a screw mounted on one of. the jaws and extending joutwardlytherefrom to form a. substantial continuation thereof, the threads of the screw being presented only beyondthe end largest where it is attached to the jaw;

4. A cork extractor comprising a pair of pivoted, levers havingaws,.one of said jaws having a plane gripping, face, the other jaw being bent to provide a concave gripping face, and a screw mountedon that jaw having the plane gripping face and extending outwardly therefrom to form a substantial continuation thereof, the threads of the screw being presentedonly beyond the end of the jaw, the curved'or concave jaw end providing a fulcrum for the implement when engaged over the mouth of the bottle -whereby a deeply driven-in cork may be started without pulling the screw out of the cork or otherwise mutilating the cork. 5. A cork extractor comprising a pair of pivoted levers having jaws, one of said jaws having a roll, a headless screw having an unthreaded portion thereof received within the roll, a. groove provided in that portion of the shank of the screw which is housed within the roll, said roll being depressed so that a portion thereof isv forced into the groove to hold the; screw against both longitudinal and rotative movement, said screw extending beyond the end of'the jaw upon which it is mounted to form a sub stantial continuation thereof.

In testimony,,that I claim the foregoing as my own, I have hereto aflixed my signature.
